slow texting

so installed the threaded txt program and love it and at first it made my text speed a lot faster but now it has gone back to the way it started and takes for ever to load a single letter i was wondering if there was a way to take off the thing that guesses what word you want to use? or if there was anyway to make increase the speed i thought overclocking might work but didnt want to sacrafice battery life i live to text and this really sucks my a$$ so please help btw i am using WM6 on my 6700
